<div>ows, FJ wants this one to come out looking as nice as possible. He decides that cow ii looks &quot;unbala</div>
<div>nced&quot; if Li and RRi differ by more than factor of 2, where LiLi and RiRi are the number of cows tall</div>
<div>er than i on her left and right, respectively. That is, ii is unbalanced if the larger of Li and Ri&nbsp;</div>
<div>is strictly more than twice the smaller of these two numbers. FJ is hoping that not too many of his&nbsp;</div>
<div>cows are unbalanced.Please help FJ compute the total number of unbalanced cows.</div>
<div>农夫约翰正在安排他的N头牛拍照片， 每头牛有一个身高，从1到N编号，排列成一行(h1,h2...hn)，每头牛i左边</div>
